Fall Urea Sprays for Apple Scab Control

It’s time to consider sanitation practices that can help reduce over wintering scab inoculum. These practices should be considered an essential part of  apple IPM  programs.

In 2014 scab was once again a problem in most orchards we scouted. Even if you didn’t see scab on the fruit at harvest there still could be infected leaves in the orchard at low levels. In addition, in the northeast and other regions scab is becoming increasingly resistant to chemistries we rely upon for primary season control. Therefore, all growers should consider integrating sanitation practices into their scab control program. The recommended sanitation program involves either: fall or spring applications of Urea; flail mowing fallen leaves; or preferably both.

For a refresher we’ve linked a short video explaining this approach.

Volunteers Needed for Brown Marmorated Stink Bug Count

Scientists at the USDA are conducting a second year of the “Great Stink Bug Count” and are looking for volunteers from NJ! They are trying to identify characteristics of houses that brown marmorated stink bugs look for when finding overwintering sites. Last year’s count had over 200 volunteers with 44 individuals who counted every day.

The basics:

  1. Fill out the form
  2. Count the BMSB on the exterior of your home each day
  3. Enter in your count data

Consider participating in the 2014 Great Stink Bug Count!

September 15 – October 15, 2014

You can download particpant forms herehttp://www.stopbmsb.org/2014-count

Results from 2013 are the first to document factors that may be important in where bugs chose to overwinter. Last year’s results suggest that landscape factors, specifically agriculture and woodland habitats, may have the greatest influence on the number of BMSB overwintering on a house.

This data will go a long way to helping us figure out important steps to managing BMSB. They are looking for citizen scientists to help out! Please fill out the attached form and send it in if you are interested!
